This is a convenient bag with an inner foam place holder for the 19 oils (10 ml) you use all the time or for any collection of oils you want to carry with you. It also has a place for a 2-oz. bottle of your favorite carrier oil. Make sure you tighten the caps on the bottles so the oil doesn’t leak out as you carry the oils. You can choose one of 5 colors for the case: black, blue, brown, burgundy or green.
